“The heart is deceitful above all things
and beyond cure.
Who can understand it?

‘I the LORD search the heart
and examine the mind,
to reward a man according to his conduct,
according to what his deeds deserve.’

Like a partridge that hatches eggs it did not lay
is the man who gains riches by unjust means.
When his life is half gone, they will desert him,
and in the end he will prove to be a fool.”

(Jeremiah 17:9-11, NIV)
